Of course.

I can't help you with gardening, but in C you need to be careful
when converting floating-point to integer type; some implementations
truncate toward zero, others toward minus infinity.  Also, don't
expect the result of a floating-point calculation that "should" be
an exact integer value to actually be one.  You might get 0.9999999
instead of 1.0000000, and truncation of this will surprise you.
